Carolynn (Carrie) Harris is PhD Student in the Environmental Science & Ecology program working with Dr. John Priscu. Carrie is an ecosystem scientist who studies carbon cycling in permanently ice-covered lakes in the McMurdo Dry Valleys of Antarctica. The Dry Valleys are the coldest, windiest, and driest desert on Earth. Despite these harsh conditions and the fact that little light penetrates the lakes’ thick ice cover, phytoplankton and microbes thrive year round. Carrie studies how biotic and abiotic processes control organic carbon transformations in the lakes. This research may have implications for if and how life could survive on icy worlds beyond our planet, such as Europa.
